Researchers in the past have studied associations of Anemia with health outcomes such as LOS & Readmission rates (see 4 studies listed at the end of the article). Similarly, we examined our database to analyze the impact on Length of Stay (LOS) when Acute Posthemorrhagic Anemia was present for major Ortho & Colorectal procedures.
The results are shown in the below chart & table.
|Category||DRG||Avg. LOS with Acute Posthemorrhagic Anemia||Avg. LOS without Acute Posthemorrhagic Anemia||Avg. LOS Difference|
|Ortho||470 - MAJOR JOINT REPLACEMENT OR REATTACHMENT OF LOWER EXTREMITY W/O MCC||3||2||1|
|Ortho||483 - MAJOR JOINT/LIMB REATTACHMENT PROCEDURE OF UPPER EXTREMITIES||3||1||2|
|Ortho||469 - MAJOR JOINT REPLACEMENT OR REATTACHMENT OF LOWER EXTREMITY W MCC||7||6||1|
|Colorectal||330 - MAJOR SMALL & LARGE BOWEL PROCEDURES W CC||8||7||1|
|Colorectal||329 - MAJOR SMALL & LARGE BOWEL PROCEDURES W MCC||16||12||4|
As the above data table shows, Ortho & Colorectal DRG procedure groups have a 1-4 day difference when Acute Posthemorrhagic Anemia was present versus when it was not present.
